Phoneme monitoring

apl92

Hi all

I'm planning on doing a novel word learning study where participants learn a word-picture pairing passively. The task is irrelevant to their learning, but keeps them occupied: they must press a button to indicate the presence or absence of a target phoneme (e.g. with target /k/, for a new word 'koba', they will indicate the phoneme is present, but absent for 'torato'). I want these words to be learnt with semantics, so in addition to performing the phoneme monitoring task, an image should be present on screen.

Following the phoneme monitoring task, I want participants to complete a 2AFC (two alternative forced choice) task. Here, two images, both learnt (one target, one a foil), are presented, and a word is heard. Participants must press either a button to indicate whether the target is on the left or right side of the screen, before a the target is presented again by itself and the word again heard as feedback.

I've been through the beginner's tutorial (and had a quick scan through the others) this morning, but none of them seem to deal with words, instead, all being about presentation of visual stimuli.

I'm not even sure where to begin here. I understand some of the basics with respect to how an experiment is structured in OpenSesame (e.g. the function of loops and sequences) but not much more.

A big issue at this point for creating the sequence would seem to be the requirement that a word and picture must be co-presented. How do I do this? Would it, for instance, be easier to glue these together into a 'video' clip (containing for instance just the one image and the sound file containing the word overlaid)?

If anyone has any resources relating to the use of OpenSesame in psycholinguistics experiments that would be very helpful also.

Hi,

> a word and picture must be co-presented

You do it just the same way as the tutorials explained. On the left of the sketchpad item, you can select one type of stimuli you can draw, just select the image tool, draw the image to wherever you want on sketchpad, select the text too, and put the text to wherever you want. As easy as that. Making a video sounds a little overly complicated.

Not sure, whether there are any psycholinguistic experiments here, but @labovich collected a number of example opensesame scripts here

Checking out some examples might be a good idea to get some inspiration.
